INDIAN A, A CORPORATION OF INDIANA GUIDE BAR non snici'ne viaonilvns Application filed February 7, 1929, Serial No. 338,133, and in Great Britain February 2, 1928.

This invention relates to slicing machines of the type in which the substance to be sliced is clamped upon a carriage which is adapted to be moved back and forth past-the slicing knife whereby slices are cut therefrom, the carriage being supported by one or morestationary guides mounted upon the baseof the machine.

' In this type of machine it is desirable to shield the guiding surfaces for the purpose of preventing grease, grit, or other foreign matter, from accumulating thereon to contaminate or roughen said surfaces.

One object of this invention is therefore to provide a covering means for the guiding surfaces to prevent the accumulation of grease, grit, and other foreign matter and this covering means preferably extends above andbelow said guiding surfaces.

Another object of this invention is to provide a lubricating means for the guide rods which will deliver the lubricant to the guide rods in desired quantities. Furthermore, this lubricating means forms part of the covering means for the guide rods in the embodiment shown but may be a separate part thereof without departing from the spirit ofthe invention.

Another object of this invention is to provide a ring surrounding the guide rod for carrying the lubricant from the trough to the guide rod.

Other objects of the invention will appear hereinafter, the novel features and combina- In the drawing Fig. 1 is an elevational view of the front part of a machine embodying my invention, with parts thereof in section for the sake of clearness; and

Fig. 2 is a side elevation, also partly in section, for the sake of clearness.

The slicing machine in the embodiment shown comprises a base 1 above which there is a carriage 2 carrying bearing members 3 slidable upon rods 4supported at their ends by upright members 5, fixed to the base. The carriage 2 has the usual cross-feed-carriage 6 7 adapted to advance the work toward. the 50 knife 10,- and has uprights 7 supportingM-a other end to the crank 12.

tions being set forth in the appended claims. I

clamping-member 8 adapted to engage'and hold the material 9 which is to be sliced, and

a handle 8 is used to manipulate the clamp 8. The knife 10 is mounted on a shaft 11 journaled in a bearing 11 fixed to the base 1.

In the operation of the machine, the carriage 2 is reciprocated along the rods 4, carrying the material 9 successively past the knife so that slicesmay be-cut therefrom as the -material is advanced to the left, as shown in .Fig. 1, toposition thematerial so that the next slicemay be cut therefrom;

-To reciprocatethe carriage, a shaft 15 is adapted to be rotated by a handle 7 mounted on the flywheel 16 directly mounted on the shaft 15. The rotation of the shaft 15 rotates the crank 12 by means of beveled gears, not

shown, since this construction iswell-known. The rotation of crank 12 causes the carriage 2 to be reciprocated on the guides 4 by means. of its connection with the carriage comprising a 'pitman 13'pivotally connected at one end to the bracket 14 integral with one of the bearings 3 and pivotally connected at its More particularly, thisinvention is concerned with the construction of the guiding means for the carriage and the protecting rounding each guide rod 4 and spaced there-' from is a tubular member 18 mounted at its length thereof for a purpose presently to be described. j

Each of thebearing members 3 has a portion extending through the slot 20, which portion has anextension adaptedto be fastened to the carriage by any suitable means, such as bolts, but these extensions may be made integral therewith, if desired. The tubular member 18 forms a cover for the guide 4 as well as providing a trough in which a lubricant may be placed for the purpose of lubricating the guide rods 4, 1

On each of the guide rods is placed a ring 21 which encircles the guide rod and extends into the lower part of the tubular member 18 so that as the ring. is rotated, it will carry with it small quantities of oil from the trough l 'means'and lubricating means therefor. 'Sur and thus lubricate the surface of the guide rod 4 and especially the upper surface where most of the weight of the carriage is received. It is desired to have a means to automatically rotate the ring only a small amount each time that the carriage is reciprocated so that only a small quantity of oil will be added to the surface of the rod. For this purpose, each of the bearing members 3 has a pin 22 extending therefrom towards the ring and spaced from the rod only a small amount so that as the carriage is reciprocated, the pins 22 alternately will engage the inner side of the ring 21 to raise the ring slightly on one side and cause it to rotate slightly about the rod 4. The bearing members 3 also cause the ring to slide along the rod 4 when it is struck by the pin 22. This distributes the lubricant along the rod instead of depositing it all at one place. The operation of this device is as follows As the handle 17 is turned, the carriage is reciprocated upon the guide rods lby means of the connections 16, 15, 12, 13 and 14, connecting the handle 17 with the carriage. The carriage is moved past the knife until the slice has been cut from the material thereon after which the carriage returns and the material is advanced toward the knife the thickness vof the slice desired to be cut therefrom. Upon each reciprocation of the carriage, one of the pins 22 engages the ring 21 tov feed the lubricant to the rod, as previously described, so that the movement of the bearing member 3 on the rod 4 is smoother than it would be without the use of a lubricant.

Obviously, it is not necessary to have the covering member mounted on the rod but this may be-supported in any manner desired and it may also be desired to dispense with that portion of the tubular member 18 which forms a cover therefor, using only that part which forms a trough for the lubricant. Or it may be desirable to use, the cover only as a protecting means for the guide rod. The slot 20 may be positioned at other places about the periphery of the tubular member without departing from the spirit of this in vention.

Obviously those skilled in the art may make various changes in the construction and arrangement of parts without departing from the spirit and scope of the invention as defined by the claims hereto appended, and I therefore do not wish to be restricted to the precise construction herein disclosed.

Having thus fully described and shown an embodiment of my invention, what I claim and desire to secure by Letters Patent of the United States is 1.
